Ohio Open (Gun) Carry Laws

Tonight I went into a local grocery store in a relatively good mood. My workday was over and the weather was exceeding warm for February, in the sixties. I went in the neighborhood grocery store to pick up a couple things we needed for the evening, milk, ketchup, etc.
My mood quickly changed when I noticed a younger, bit overweight man browsing an isle. He was in jeans and a sweatshirt, no sign of any kind of uniform or marking on his chest. I was watching him because I noticed what was on his belt. At first I thought it may be some other kind of device, because I was looking at three clips. But as I saw his other side, I saw the handgun on his right. He as walking slowly away from me and I just stopped and stared, without realizing what I was doing. When he got out of sight and checked out I resumed getting the groceries I came for, but in a much different mood. I found myself inspecting everyone around me much more carefully, looking around isles before stepping out. I was feeling fear, fear of other humans.
I have to ask, how is it that people feel safer this way? It has never made me feel safer to see ordinary citizens with guns, only more fearful.
Ohio is and has been very liberal in its gun laws; practically anyone can carry a gun almost anywhere, except in places with alcohol, and there is some restrictions in motor vehicles. Below are some relevant links:

Consumerism and family

All three of our boys, and our daughter-in-law, have worked in retail. Modern day retail establishments are open nearly all day, most seven days per week. This means that many hours will be worked at odd hours of the day, and weekends, especially for newer workers, lower on the totem pole. To make it worse, schedules usually change in retail for the workers from week to week, so that the retail employee never knows his or her schedule more than one week out.
The effect is that there is no family continunity. Meals can never be planned much in advance. There is no ‘normal’ rhythm to the family for any kind of routine activities, be it work, meals, or recreation. I feel this can only affect family fabric in a negative way.
The next time you go out of a retail store late in the evening or on the weekend, give that some thought, how you are supporting the continued fragmentation and dissolution of the American family.
